Beginning this past Tuesday, travelers on US 101 and US 12 in Aberdeen and Hoquiam experienced nighttime traffic signal changes.

The Washington State Department of Transportation converted all the traffic signals on US 101/US 12 from the Wishkah River Bridge to Hoquiam in all directions to standard “green-yellow-red” signals, which will have them operate the same as they do during the day, according to a press release.

Using the regular “green-yellow-red” signals during the night will clarify right of way for all users along the corridor. Drivers on the side street will be able to cross or make a turn onto US 101/US 12 with a green light rather than yielding to highway traffic. Pedestrians will be able to cross on a “Walk” signal in the same manner as the daytime.

These traffic signals have detection to trigger side street greens and pedestrian “Walk” signals. Travelers will approach the traffic light on a side street and see a solid red light, or a “Don’t Walk” sign, but once detected will receive a green light or a “Walk” signal. Once the side street or pedestrian traffic is gone, the main highway signal will revert to green and remain there until more side street traffic approaches.
